Population Dynamics of Bullet Tuna (Auxis rochei Risso 1881) from the Indian Ocean, West Nusa Tenggara, Indonesia by Evron Asrial, Ruly Isfatul Khasanah, Fathurriadi Fathrurriadi, Yasir Arapat, Usma Kurniawan Hadi, Lalu Achmad Tan Tilar Wangsajati Sukmaring Kalih, Lalu Samsul Rizal, Mita Ayu Liliyanti, Erwin Rosadi, Daduk Setyohadi, Muhammad Junaidi, Ishani Nelunika Rathnayake

“…Highlight Research: • The bullet tuna (Auxis rochei) was identified and analysed. • The length at first maturity (Lm) of bullet tuna (Auxis rochei) was analyzed • The eligibility status of bullet tuna (Auxis rochei) has been analyzed and estimated • The LWR curve can be used to estimate age groups of fish compared to the sigmoid curve • The CF cannot be automatically used to estimate fish worth selling   Abstract The bullet tuna (Auxis rochei), BLT or tongkol lisong (Indonesian) is a species of neritic tuna which is one of the target fish for small scale fishers. …”

Growth and Population Parameters of Panulirus penicillatus and Panulirus homarus in Labangka Tidal Waters, Indonesia by Evron Asrial, Erwin Rosadi, Hamid Hamid, Muhammad Ichsan, Ruly Isfatul Khasanah, Naning Dwi Sulystyaningsih, Agustin Dwi Sumiwi, Najiah Khalisah

“…While, attributes that have improved are carapace length at first capture (CLc) longer than 50% carapace length of infinity (0.5CL∞) and CL rate (CLc/0.5CL∞) reaching more than 1.00 (CLR > 1.00). In implementing sustainable management of spiny lobster for fishery resources, improvisation is needed in place of catching technologies. …”

Influence of TiN inclusions and segregation bands on the mechanical properties and ballistic performance during ballistic impact tests in low-alloy high-strength steel by Keke Tong, Haoran Sun, Luxing Duan, Xiurong Zuo

“…With ballistic test at a bullet impact velocity of about 810 m/s, the steel plate displayed the different ballistic performance, forming partially penetrated crater A and the completely penetrated crater B, despite the craters A and B were close together with only about 100 mm. …”

Experimental and Numerical Simulation to Validate Critical Perforation Velocity on a Flat Plate Aluminium Alloy 6061 by Bharosh Kumar Yadav, Mehdi Jahangiri, Dalbir Singh

“…According to the study’s findings, the critical perforation velocity was found to be 70 ms−1 when a flat-nosed bullet (45 mm length and 12 mm diameter) made of stainless steel weighing 50 grams was fired normally to the center of a square plate specimen of Al6061 alloy. …”
